KANSAS CITY, Mo. — Charlie Weis is back in the NFL. Barely a month after getting fired at Notre Dame, Weis signed on Friday as offensive coordinator with the Kansas City Chiefs, where he’ll join two old friends in trying to revive a flagging franchise that’s won only 10 games in three years.

“This marriage seemed very, very simple,” Weis said. “I’m very excited to be a part of a growing process that has been started here in the last year.”

In an interview on Wednesday, Weis virtually confirmed that he was about to rejoin head coach Todd Haley and general manager Scott Pioli.

Pioli was a front office executive in New England when Weis was offensive coordinator for the Patriots’ four Super Bowl teams, and Weis shared a small office with Haley for three years when they were assistants with the Jets.

“My relationship with Todd and my relationship with Scott and several other persons in the organization made Kansas City look like a fine landing spot for me,” Weis said. “I couldn’t be more pleased.”
